Borehole Density Measurements – Geophysical Logging OVERVIEW: Geophysical borehole density logging is a rapid, cost effective and accurate method to obtain bulk density values for ore modelling. In many mineralisation styles, the density value can be related to the ore grade. Outside of ore grade the bulk density measurements can be used for overburden stripping […]
Formation Density Logging – Coal Blasthole Logging
BLASTHOLE LOGGING IN COAL BLASTHOLE LOGGING IN COAL PROJECT & GOALS: Identification of coal seam parameters (density, top boundary, bottom boundary and partings) within pre-split blastholes prior to blasting. BLASTHOLE LOGGING IN COAL DATA SETS: Gamma, dual spaced density, borehole diameter and magnetic deviation data are acquired, rapidly and cost effectively in blastholes Data in […]
Formation Density Logging – Overview
DENSITY LOGGING DENSITY LOGGING APPLICATION: Measurement of the formation involves a small radioactive source (CS137 or CO60) acting as a gamma radiation source to induce back scattering of gamma radiation in the formation. The back scattered gamma energies are detected at a range of scintillation detectors (typically two but can be three detectors) within a […]
